Pregunta abierta 1
Modify the second data set and consider whether one center of distribution (one of the means) is much higher than the other, or if the centers (the means) are close together. How do the centers of distribution compare across the data sets of the dot plots in the following cases? a) The difference in the means is less than 2 MADs b) The difference in the means is more than 2 MADs
